Structural Analysis by Modified Signature Matrix for Integro-differential-algebraic Equations
Wenqiang Yang, Wenyuan Wu, Greg Reid
Integro-differential-algebraic equations (IDAE)s are widely used in applications of engineering and analysis. When there are hidden constraints in an IDAE, structural analysis is n…

Index Reduction for Degenerated Differential-Algebraic Equations by Embedding
Wenqiang Yang, Wenyuan Wu, Greg Reid
To find consistent initial data points for a system of differential-algebraic equations, requires the identification of its missing constraints. An efficient class of structural me…
